The quantities A and B are related by the relation A//B=m, where m is the linear density and A is force, the dimensions of B will be :

Answer»

same as that of pressure
same as that of work
that of momentum
same as that of latent heat

Solution :`(A)/(B)=m:.B=(A)/(m)=("FORCE")/("LINEAR density")=(MLT^(-2))/(ML^(-1))`
`:.B=[M^(0)L^(2)T^(-2)]`
`Latent heat=("Heatenergy")/("mass")`
`=(ML^(2)T^(-2))/(M)=[M^(0)L^(2)T^(-2)]`
Thus `B` has same dimensions as that of latent heat.
So cannot choice is `(d)`.
